JokerJack is a hypnotically additive deckbuilder that takes the classic game of 21 and cranks it to the breaking point. Forget everything you know about playing it safe; here, "busting" is just a missed opportunity for a massive multiplier.

Combine the fundamentals of Blackjack with a growing collection of over 60 unique Joker cards to create game-breaking synergies. Whether you're adding flat chips for every Face card played or triggering an exponential Multiplier for hitting exactly 21, your goal is simple: reach the target score, survive the Blind, and keep the run alive.

With seeded runs, deep strategic discards, and a retro-neon aesthetic, every hand is a fresh chance to find the ultimate combo. Do you have the strategy to outsmart the deck, or will you go bust trying?
